title: Bis(2,2',2''-nitrilo-triacetamide-κ(3) O,N,O')cobalt(II) dinitrate tetra-hydrate.
abstract: In the centrosymmetric title compound, [Co(C6H12N4O3)2](NO3)2·4H2O, the Co(II) ion, lying on an inversion center, is O,N,O'-chelated by two nitrilo-triacetamide mol-ecules, forming a distorted octa-hedral geometry. In the crystal, extensive O-H⋯O and N-H⋯O hydrogen bonds link the complex cations, nitrate anions and lattice water mol-ecules into a three-dimensional network.
